PROFINET – Why Choose it?

Last March I posted details from the PROFINET Executive Leadership Forum that we held in Miami the month before: PROFINET Executive Leadership Forum and PROFINET Executive Leadership Forum Day 2 I recently rediscovered the video that was made of GE Intelligent Platforms’ Bernie Anger at the forum.  He talked about influences he expected to impact…

Catching the Process Fieldbus

This is an updated, edited version of the book review post from March of 2009. I once blogged with tongue in cheek that not only did we have more installed nodes of PROFIBUS than any of the other fieldbuses, but that we had more books, too.  Now we have one more and it’s a doozey. …

SPS 2012: IO-Link

IO-Link also featured prominently in the PI Booth. Our relationship with IO-Link is a bit peculiar. The consortium responsible for IO-Link relies on the PI infrastructure. If you have not encountered IO-Link before, I call it HART for discrete because it superimposes the digital communications over the three-wire DI/DO cable. IO-link is therefore not a…

SPS 2012: PROFIenergy

PROFIenergy is a big deal. It’s one of the really big benefits of using PROFINET. Products have been available for some years now and they are starting to appear in very large projects in the automotive industry. At the PI press conference Michael Lebrecht of Daimler presented their ongoing project using PROFIenergy. During the Q&A…

SPS 2012: PROFIBUS and PROFINET in Process

Did you notice in the post about the PI Booth that there were two process walls in the booth? One was for PROFIBUS and the other for PROFINET! If you look closely you may also notice Foundation Fieldbus, HART, and WirelessHART. All of these can have a potential role in a PROFINET/PROFIBUS architected system. On…

SPS 2012: PROFIdrive

PROFIdrive is an application profile that sits above the PROFIBUS and PROFINET communications protocols. It arranges the data in a consistent fashion to simplify the interchange of information. Drive vendors can choose not to use PROFIdrive, but then the drive parameters are not so easily exchanged. To make it easier for drive vendors to adopt…

SPS 2012: PROFINET Chips

I continue to be amazed at the number of chip-based solutions available for PROFINET. I’ve lost count of the actual number. But Innovasic, KW-Software, and Hilscher were in the PI booth with their solutions. Molex was in the booth, too, and they announced a partnership with profichip for a PROFINET solution. I walked over to…

SPS 2012: PROFINET Faster

PROFINET was, of course, all over the show, including in the booths of companies that own or sponsor competing Industrial Ethernets! PROFINET’s theme in the PI booth was that PROFINET does more. It is faster now with 31.25 microsecond update times, but there’s a lot more to PROFINET. Like the only Industrial Ethernet with released…
